Fractions are just shy decimals wearing costumes. If someone hands you ⅘, you have two options. Option one: turn it into a decimal (⅘ = 0.8), then multiply by 100 to get 80%.
Option two: just multiply the fraction by 100 directly. Yes, you can do that. So ⅘ x 100 = 400/5 = 80. Same answer, fewer steps. You’re welcome.
If you’re feeling fancy, you can also use a shortcut: move the decimal point two places to the right. That’s literally multiplying by 100 without writing anything down. Magic, right?

What About Tiny Numbers? Like 0.003?
Even the small fries get love. Multiply 0.003 by 100. You get 0.3. So 0.003 = 0.3%.
Yes, that’s a fraction of a percent. It means you’re part of a very exclusive, very tiny club. Congratulations. Just don’t use it to brag at parties.
